A brief description of when and why the water use baseline was adopted:

2018 Note: Updated baseline data. After an extensive review of current and historical water use, it was decided that our previously reported baseline numbers were not reflective of total campus water use (likely did not include non-potable irrigation from the main lake and non-potable irrigation from the Golf Course lake). Using historical water bills for potable water use and records from our pump house readings for non-potable lake irrigation, we have meticulously recalculated the baseline year (Fiscal year July 1, 2004 to June 30, 2005) and have reported these more accurate numbers with this submission. We used the same method to calculate current performance year numbers and will continue this practice moving forward.

2021 Note: We made the decision to exclude the golf course from our STARS report as we don't consider it a part of "main campus. It was also excluded in the institutional boundary (PRE-3). Therefore, the baseline water withdrawals were updated again, subtracting a 5 year average for golf course irrigation. Based on this change, our 2005 Baseline gallons went from 156,644,000 to 141,396,000 total withdrawal; and 115,100,000 to 114,852,000 potable withdrawal.

A brief description of the institution's water-related behavior change initiatives:

A brief description of the institution's water recovery and reuse initiatives:

One of our biggest projects is the closed-loop solar/aquatic waste water treatment system in the Charles Townes Science Center. The living machine uses natural processes in a series of artificial tidal pools to clean up to 5,000 gal/day of the building’s waste water. It is then re-circulated into the building as grey water, which can be used for non-potable water demands like flushing toilets.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

We continue to use Furman Lake to supplement irrigation on campus, reducing our potable water irrigation to 40%.

Original Baseline vegetated grounds (745 acres) is referencing the entire main campus acreage and is an overestimate for vegetated grounds. A more accurate estimate is 420 acres of vegetated grounds, assuming that some amount of acreage has been developed since 2005.

Current vegetated grounds includes: main campus managed grounds and forests.

The FY2020 data is likely highly impacted by COVID-19 reduced campus operation from mid March 2020 - June, 30 2020. Therefore, FY 2019 water withdrawal data is reported.
